MUSIC-LEAF TURNER. AND MUSIC-PORTFOLIO.

Application filed June 7, 1915.

To all whom it may concern:

lilo it known that l, KrnnsHiNsi-m K. su 'ect of the King of Great )l'tillll, lQSL 11g at Jubbulpore, Central Province, India, have invented certain new and useful Improvements in Music-Leaf ers and Music-Pca'tfolios; and I do L the following to be a full, clear, and exact description of the invention, in the art same.

'lfhis inv "ion relates to improvements in music ml turners.

The pri lpal object of the invention is music leaf turning device which can be readily placed on the music rest of a piano r on a portable music stand.

Another object is to provide a music leaf turner which is simple in construction, ef

fective in operation and one which can be readily folded and carried from place to place.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a front elevation of my music leaf turner in open position,

Fig. 2 is a horizontal sectional view of the device on the line 22 of Fig. 1,

Fig. 8 is a vertical sectional view taken on the line 83 of Fig. 1,

Fig. 4 is an enlarged detail perspective view of the inner end of one of the leaf turning arms,

Fig. 5 is an enlarged detail view of the leaf engaging portion of one of the arms,

and showing a portion of a music leaf in operative position relative thereto,

F 6 is an enlarged perspective view of the lower end of one of the operating rods.

Referring particularly to the accompanying drawing, the back of the device is similar to the lack of a book, and includes the parts 10 and 11 connected together by the binding hinge 12, the latter being formed preferably of leather. Secured to the inner face of the binding 12 and at the upper end thereof is a substantially U-shaped bracket 13, the same extending outwardly from the binding and in vertical position longitudinal of the binding. A plurality of leaf turning arms are mounted on the bracket Specification of Letters Patent.

Patented Mar. 27, 1917.

Serial No. 32,792.

13, each of which is formed of two wires 1% and The inner ends of the wires let and are coiled around the bracket 13 to form a pivotal connection therewith, the attaching points of said wires being vertically spaced from each other as clearly shown. Coiled about the bracket 13 between each pair of wires 1t and 15 is a spring 16, one end of which is secured to the wire 15, while the other end bears against the board 10. The other end of each of the wires 1% and 15 turns downwardly as shown at 17 and 18 respectively, the former of which is provided with a pivoted joint 19. Embracing the downturncd ends of the wires is a ring 20 which is arranged to be slipped dmvn below the joint 19 to prevent movement of the joint, a music leaf 21 being engaged between the downturned ends, as clearly shown. Depending from the inter mediate portions of the arms are the detents 22, these being arranged at different distances from the ends of the arms. Slidably mounted on the board 11 and disposed in the block 23 are the longitudinal operating rods 241, the upper ends of which are bent outwardly and upwardly as at 25 in position to engage'the lower ends of the detents 22. The lower end of each of the rods 24 has pivotally connected thereto an outwardly extending arm 26, the pivotal or hinged connection being provided with the abutting stop lugs 27 and 28 which hold the said arms in extended position away from the board 11, but which permit the arms to be folded inwardly against the lower ends of the rods, when the boards 10 and 11 are to be folded together in the semblance of a hook.

Pivotally mounted on each side of the parts 10 and 11 and at a suitable distance from the lower ends thereof are shelves or ledges 29 on which the music is adapted to be rested. Pivoted to the lower portion of the binding 12 is a rod 30, the upper end of which is adapted to engage with a keeper 31, this rod being arranged to hold the hinge or binding portion of the music.

In the operation of the device, a piece of music is rested on the ledges 29, when the boards 10 and 11 are opened and rested on the shelf of a piano or a music rack, after which the rod 30 is engaged with the middle portion of the music and fastened to the keeper 31. The arms are swung to the right hand side against the board 11 and held by the engagement of the detents 22 with the operating rods 2%. To attach the arms to the leaves of the music, the ring 20 is slipped above the joint 19 so as to permit the lower end of the downturned portion 17 to be swung outwardly. The leaf is then laid against the remaining downturned portion and then the first portion swung downwardly against the outer face of the leaf and the ring again slipped down below the joint. The edge of the leaf is thus clamped between the downturned portions 17 and 18. This is repeated with each leaf and arm until all of the leaves are engaged for tur ing. The arms 26 are then swung outwardly, as shown on the drawings. By pressing down on the innermost of the arms 26, the lowermost of the leaf turning arms will be released and thrown against the board 10 by means of its spring, carrying the attached leaf with it. This is repeated with the remaining arms 26 until all of the leaves have been turned.

To prevent noise by reason of the constant contact of the arms with the board 10, a strip of rubber 32 is attached to the upper portion of the board 10.

By folding up the ledges 29, and turning upwardly the arms 26, the boards 10 and 11 may be folded over toward each other so that the device will have the appearance of a book.

Suitable clasps (not shown) may be provided for holding the boards in folded position. Buttons 33 are provided on the up- Copies of this patent may be obtained for per ends of the arms 26 for a purpose which is obvious.

What is claimed is:

1. In a music leaf turner, a leaf holding element comprising a pair of wire arms each having an eye at one end and each provided with an outer downturned portion, said downturned portions coacting to form a leaf clamp, one of said arms having its downturned portion integral throughout and the other arm having the lower part of the downturned portion hinged to the upper part thereof, and means on the arms to force the extremity of said lower part toward the eX tremity of the other arm.

2. In a music leaf turner, a leaf holding element comprising a pair of wire arms, each having an eye at one end and each provided with an outer downturned portion said downturned portions coacting to form a leaf clamp, one of said arms having its downturned portion integral throughout and the other arm having the lower part of the downturned portion hinged to the upper part thereof, and a ring embracing said downturned portions and slidable thereon to force the extremity of said lower hinged part toward the extremity of the other arm.

In testimony whereof, I afliX my signature, in the presence of two witnesses.
